FLANGlNG-IVIACHINE.

SPECIFICATION forming part of Letters Patent No. 761,918, dated June '7, 1904.

Application filed December 12,1903. Serial No. 184,880- (No model.)

To all whmn it may concern:

Be it known that I, THQMAS F. ROWLAND, J r. a citizen of the United States, and a resident of the borough of Brooklyn, city of New York, county of Kings, and State of New York, have invented certain new and useful Improvements in Flanging-Machines, of which the following is a specification, taken in connection with the accompanying drawings.

This invention relates to flanging-machines, and relates especially to machines for forming the end flanges on corrugated furnaces.

In the accompanying drawings, Figure 1 is a plan view of a flanging-machine embodying this invention. Fig. 2is a longitudinal vertical section of the same. Figs. 3 and 4 are partial transverse vertical sections showing the parts in different positions.

In the embodiment of this invention shown in the drawings a rigid frame is formed for the operating parts of the machine, this frame comprising the bed 1 and the pillar 17. This pillar is adapted to support the power-actuated fianging-head 24, which preferablyhas a fixed line of movement, this line of movement being angularly disposed with relation to the bed, I

as indicated in the drawings. This head is shown secured to the piston 20, operating within the cylinder 2, this cylinder being provided with a suitable stufling-box 23 at its lower end and being operated by fluid under pressure-such as water, steam, or other fluid which may be admitted as desired through the port 21 to the space 25 above the piston'or through the port 22 to raise the flanging-head.

Suitable means are provided on the bed to support a furnace, so that it will cooperate with the flanging-head. In thedrawings the corrugated furnace 50 is shown as rotatably supported, resting upon a series of antifriction supporting-rolls 5, which may be revolubly mounted upon suitable shafts 4, extending longitudinally of the machine .at either side of the same. These shafts are preferably laterally adjustable and for this purpose may be rigidly secured in the blocks 11. Each of these blocks may be adjusted, as shown in Fig. 1, by turning the screw 12, engaging the block and swivelingly mounted in the lug 13, and in this way the supporting means may be furnaces on the machine.

adjusted to accommodate furnaces of different size. Aliners are preferably employed to secure the exact longitudinal position of the Aliners in the form of rolls 6 may be used, and, as indicated, each of these aliners is rotatably mounted in the sleeve 14, loosely engaging the shaft 1. Each alining-roll and its sleeve may be thus angularly and longitudinally adjusted so as to properly coact with the furnace and may be rigidly secured in desired position'by the bolt 31, which clamps the sleeve to its shaft. In order to more securely maintain the furnace in position and prevent the furnace end from rising, a holding-lever 10 may be employed,

this lever being preferably pivoted about the pin 29 in the standard 9, which is secured to the bed. This lever ispreferably provided at its forward end with the holding-roll 7,

which engages the rear end of the furnace.

It is desirable in operating this flangingmachine that the anvil which supports the furnace and which cooperates with the flanging-head be rigidly supported at all times and also that it be of adjustable height, so as to form flanges at different distances from the wall of the furnace. This is of special importance where the end flange of the furnace is not concentric with the body of the same, buthas an irregular shapesuch, for instance, as is indicated in the drawings-this type of furnace being quite common in marine work. To accomplish this purpose, the anvil 3 may be given any form, so as to have a varying height at various parts of the same, and may be formed as indicated inFigs. 3 and L, and this anvil may be mounted to' be adjusted transversely of the machine by any suitable means, so that'the operative portion of the anvil adjacent the ,flanging-head is of the height desired. As indicated, the anvil 3 is formed with the guide 27, which cooperates with asuitable groove in the bed ofthe ma chine, and this anvil is engaged by the adjusting-screw 18, swivcled in the lug 15, formed on the projecting portion 1 1 of the bed. This screw may be operated by a suitable wheel 16 or by any other means, so as to properly adhold it in position. The support 8 may be used adjacent the anvil and properly secured to the bed, so as to support the adjacent face of the anvil.

In operating this machine the furnace 50, which may have the flange 51 roughly formed at one end of the same, is mounted upon the supporting-rolls, the aliuers being properly adjusted and fixed in position. The flange may then be heated in Whole or in part to the desired extent, and the varying-height anvil is moved transversely, so as to support the flange 51 at the desired height. The flanginghead 24 is then operated hydraulically or in any other Way to finish one portion of the flange by firmly pressing it down against the side of the anvil 8. The furnace is then retated by hand or by any other suitable means, and as it is rotated the anvil height is adjusted by the means indicated, the flanging operation being continued, so that each portion of the flange 51 is operated upon and the flange is finished throughout its entire extent. The range of adjustment of the anvil 3 necessary for forming the flange shown in the drawings is indicated in Figs. 8 and 4.

It is of course understood that many modifications in the form, proportion, and number of parts of this machine may be made by those familiar with this art. Furthermore, parts of the same may be used Without employing the whole, and parts may be used in connection with other devices without departing from the spirit of this invention or losing the advantages of the same. I do not, therefore,

desire to be limited to the details of the disclosure which has been made in this case; but

What I claim as new and what I desire to secure by Letters Patent is set forth in the appen ed claims:

1. In flanging-machines, adjustable longitudinal shafts carrying supporting rolls,

aliuers cooperating with said shafts to rotatably support a furnace, a holding-lever ad acent said aliuers to hold said furnace in position, a transverselyadjustable rigidly-supporting anvil of varying height to support a flange on said furnace, an angularly-arranged cylinder and a flanging-head operated by said cylinder and cooperating with said anvil to form said flange.

2. In Hanging-machines, longitudinal sha fts carrying supporting-rolls, aliners to rotatably support a furnace an anvil of varying height, means to transversely adjust said anvil to bring various parts of the same into o mrative position, said anvil being rigidly supported during the operation of the machine and a poweractuated flanging-head co(' 1 erating with said anvil.

3.- In flanging-machines, a frame, means mounted on said frame to support a blank, a power-actuated Hanging-head mounted on said frame and an anvil movably mounted in a transverse guide in said frame to bring the various parts of said anvil into co peration with said head and adjust the height of said anvil with respect to said head while rigidly supporting said anvil in operative position.

4. In flanging-machines, a frame, machines mounted on said frame to rotatahly support a furnace, a power actuated ilanginghead mounted on said frame and having a fixed line of movement, an anvil of varying height mounted in a transverse groove in said frame and means to adjust the position of said anvil to bring the various parts of the same into cooperation with said head and to hold said anvil in operative position.
